Roller Type Servo Voltage Stabilizers are auto wound transformers having single layer helical-coil mounted on a conventional laminated core. L D Power Transformer [p] Ltd. Manufactures Roller Type Servo Voltage Stabilizers.
L D Power Transformer [p] Ltd. Is an ISO 9002-2000 awarded company that also manufactures all special type Transformers from 10 KV A to 5000 KV A in class and servo voltage Transformers. Roller Type Servo Voltage Stabilizers consist of self lubricating carbon rollers assembled on bakelite carrier boards that traverse the length of the coil track. The roller mechanism is driven by the servomotor, which receives its signal from a voltage monitoring IC card on the output side of the servo stabilizer.
